In the case of the blockchain fee transaction method using an intermediary point according to the present invention, as shown in FIG. 3, a business operator or an individual operating a decentralized application on the blockchain based on a blockchain platform ("DApp For convenience, "operating business or individual" will be collectively referred to as "business". The same shall apply hereinafter) to provide services for each purpose to service users by operating DApps.

Accordingly, service users who use DApps pay the fees required to use DApps.In this process, the fee incurred when using the DApp with service users and the payment and transaction mechanisms for virtual assets (Cryptocurrency) required for use of the blockchain platform are described below. I will explain.

First, as shown in Figures 3 to 6, it will be described based on the blockchain platform.

In the case of the blockchain fee transaction method using an intermediary point according to an embodiment of the present invention, as shown in Figs. 3, 4, 5, 6 and 9, a decentralized application (dApp) on a blockchain platform. ) As a method for trading blockchain fees using (key cryptocurrency) points that mediate the key cryptocurrency of the service provider through (S10) Depositing in a wallet, converting to points at a predetermined rate, and storing them; (S20) the step of using the resources of the blockchain platform through the service user of the DApp; And (S30) a step in which a predetermined portion of the points stored in the operator's electronic wallet is paid to the node operator.

First, the operator, that is, the side that provides the service through the DApp, preemptively pays the key virtual asset for the fee required for the use of the resources of the blockchain platform, and deposits it in its own dedicated electronic wallet 20.

In the case of key virtual assets deposited by prepayment by a business operator, they are deposited in their own dedicated electronic wallet, which means a dedicated account for depositing the business’s key virtual assets. For this reason, in the case of DApp service users, unlike the conventional Ethereum blockchain platform-based fee payment mechanism, the first basic virtual assets are paid and stored in their own electronic wallet. There is no need to be rough.

As shown in Figs. 6 and 9, a business operator has a pre-deposited key virtual asset (2) in proportion to the key virtual asset in which another type of key virtual asset, a point, is deposited in the electronic wallet. It is stored symbolically. In this process, the resources of the blockchain platform are used, so the operator can pay the underlying virtual assets to node operators at an initial cost.

As shown in Fig. 13, points (3) as well as key virtual assets (2) that a business operator initially pays and purchases can be understood as key virtual assets, and points (3) compared to these key virtual assets (2) The storage ratio of may be set to be constant. In addition, this point (3) storage ratio can be made in proportion to the change in the value of the underlying virtual asset (2) with respect to the legal currency (won or dollar). Of course, the storage ratio of the points (3) to the base virtual asset (2) can be set and changed automatically by the manager or by a predefined management system if necessary due to changes in value.

In other words, even if the value of the key virtual asset (2) changes compared to the legal currency, the conversion ratio of the points (3) to the base virtual asset (2) is stored in proportion, so the point (3), that is, the fee price is indirect. It can be formed as a concept that is kept constant.

Here, assuming that the point is a fixed price relative to the fiat currency (e.g., dollar), for example, 1 point is set to be 0.01 dollar, if the market price of 1 base virtual asset is 1 dollar, 1 base virtual asset is converted to 100 points. In addition, even if the market price of the first base virtual asset is 10 dollars, the first base virtual asset is also converted to 1000 points.

The base virtual asset (2) used the resources of the blockchain platform in the process of converting to points (3), and accordingly, payment of the initial cost according to the initial point (3) conversion to each node operator through the virtual asset (2). As paid, the points 3 are deducted accordingly, and the conversion process from the base virtual asset 2 to the points 3 is performed irreversibly. Accordingly, the inverse transformation from the point 3 to the base virtual asset 2 is prevented from proceeding.

The individual fee required for the use of the DApp is that the service user pays the fee and purchases a coin such as dApp#1 coin according to the fee system required by the DApp itself.Through the purchased dApp#1 coin, the service user pays the dApp usage fee. Payment, and accordingly, the business operator generates a profit from the payment of dApp #1 coin.

As shown in Figure 9, in the case of (S10) step, (S11) the step of opening an electronic wallet assigned to the operator by the operator; (S12) the step of payment of the virtual asset by the operator; And (S13) depositing the paid virtual asset in the operator's electronic wallet.

In addition, as shown in FIG. 9, in the case of step (S10), (S14) storing points at a predetermined ratio to the virtual assets deposited in the electronic wallet; And as shown in FIG. 7, (S15) when the virtual asset is stored in points at a predetermined ratio, an initial cost corresponding to the use of the resources of the blockchain platform may be paid to the node operator.

Here, the concept that the initial cost, which is the key virtual asset of the blockchain platform, is paid to the node operator, should be understood as the concept of a dedicated account for the payment of the virtual asset, which is the key virtual asset assigned to the node operator, as well as the node operator's electronic wallet.

As shown in Figure 10, (S20) step (S21) the step of signing up as a member of the service of the DApp by the service user; And (S23) may include the step of using the service of the DApp by the service user.

In other words, the service user uses the service of the DApp. In this process, the service user signs up as a service user of the DApp, and then purchases a separate coin provided by the DApp, such as dApp #1 coin, to use the service of the DApp. In this case, the service user pays fiat currency and purchases a separate coin provided by the DApp after step (S21).

Here, after the step (S21), (S22) a step in which a separate coin, such as dApp#1 coin, provided by the dApp by the service user, is paid and purchased, or a step of obtaining by other methods may be further included.

Here, in step (S22), a separate coin paid for and purchased by the service user or obtained by other methods is deposited in the individual electronic wallet of the service user.

Service users can purchase only the coins required by dApp #1, such as dApp #1 coin, or acquire and use them through other methods in order to use the dApp #1 provided by the operator #1. After depositing in your own wallet, there is no need for cumbersome processes such as separate use of service fees and fees.

As shown in FIG. 8, the cost according to the resources of the blockchain platform used when the service user uses the DApp is deducted from the converted point 3 deposited by the DApp operator and paid to the node operator.

As shown in Figure 11, (S30) step (S31) in response to the use of the resources of the blockchain platform by the service user, the step of paying the points stored in the operator's electronic wallet; (S32) deducting points from the operator's electronic wallet as much as the amount paid to the node operator; And (S33) may include the step of paying the deducted points to the node operator.

That is, as described above, the point 3 also corresponds to a key virtual asset, and the point (3) converted by the operator deposits the resource utilization of the blockchain platform and fees generated by the service user's use of the DApp service. ) Is paid in the corresponding amount. Of course, in this process, not only can a quantitative evaluation of the portion of which the resource is used, but also which of the resources each resource is used can be quantitatively evaluated. It may be paid equally to the node operator corresponding to the resource, or may be paid proportionally or interlocked with it.

As shown in Fig. 12, it is not necessary for only the operator to pay for the base virtual asset 2 in advance, purchase it, and deposit it. It goes without saying that the service users, not the business operators, can also purchase the key virtual assets 2 and deposit or recharge them in the electronic wallet, which is an exclusive account of the business, in the form of donation, transfer, transfer, etc. to the business.

The scope of the rights of the present invention is determined by the matters described in the claims, and the parentheses used in the claims are not described for selective limitation, but are used for clear elements, and descriptions in parentheses are also interpreted as essential elements. It should be.
